WebMar 30, 2024 · The electron-hole mobility ratio in Germanium is \(\dfrac{3800}{1800}\) = 2.11 : 1 ≈ 2 : 1. Important Points. The mobility of electrons and holes depends on their effective masses. The effective mass of electrons is less than that of holes hence electrons have higher mobility than holes. WebApr 10, 2024 · Calculation of the hole effective mass and the spin–orbit splitting energy also showed comparable values to crystalline Ge. The conclusions of this study were that the valence band of the a-Ge is not much different from that of c-Ge and the wave-function of the valence band is non-localized as in c-Ge. 9–11 9. J. Tauc, Science 158, 1543 (1967).
